I tried out FreeBSD 6.0 (sorry, I copied just part or
uname -a and I got something like "LINUX 2.4.2 FreeBSD 6.0 -
Release #0: Nov 3 09:36:13 UTC 2005 i686 i686 i386 GNU/LINUX")
and was surprised to find that things in the echo command didn't
work. When I typed
echo "a\tb"
I got a\tb , no tab replacing the "\t" Same for "\n".
When I tried to type
echo "<tab>b"
where <tab> stands for hitting the tab key, when I hit <tab> the
first time, nothing happened, when I hit it immediately afterward, I
got an ls -A listing. I did manage to get a tab into the string
by typing something else there in place of tab and then editting
the command with r (the replace function) to put a tab in it.
When I hit <tab> similarly immediately after the command
prompt I got a question asking if I wanted to see the 424 (or was it
242 ?) possibilities and the computer responded immediately after a
'y' or 'n' key was hit.
How could this happen? The echo command (and builtin , I
tried both [and I presume that echo by itself invokes the builtin ])
should be standard?
